2016 Life-Cycle Assessment for Mobile Phones

Life Cycle Assessment for Mobile Products
Background
Samsung has developed strong technical experience in assessing the life cycle environmental impacts of its smart phones. The most recent
life cycle assessment (LCA) has been for the Samsung Galaxy S6; Note5; Tab E model. The assessment considers potential environmental
impacts across the whole life cycle including; pre-manufacturing; product manufacturing; distribution; product use; and disposal phase.
To ensure technical quality; the analysis methodology has been completed according to international standard ISO 14040 series. Samsung
has used Simapro7 software and a dedicated LCA S/W database to measure environmental impacts using a wide range of data categories
including; Product bill of material (BOM), parts and components logistics, energy consumption in product use and end-of-life scenario data in
order to attain the highest level of accuracy. The outcome of the LCA confirmed and quantified 12 potential environment impact categories
including; global warming; abiotic depletion; ocean acidification; eutrophication; and ozone layer depletion; where each impact category has
been assessed for each life cycle stage. These LCA results will continue to be considered during product development phase as we aspire to
improve the environmental specifications of our products.
